BCI’s Battery Technology Divisions serve as strategic platforms for innovation, collaboration, and market acceleration within emerging or sub-sector energy storage technologies.


The BCI Flow Battery Industry Group (FBIG) serves as the focal point within Battery Council International for flow battery technology, policy, manufacturing, and market development. As the energy storage landscape evolves and demand for grid scale storage grows, flow battery manufacturers and suppliers are playing an increasingly important role in the North American battery supply chain.
Through FBIG, BCI provides flow battery industry stakeholders with a dedicated forum to monitor and respond to North American manufacturing and market opportunities, foster supply chain growth, advance safety protocols and best practices, and develop the standardized test specifications, component definitions, and consensus terminology that this maturing industry requires.


The BCI Separator Manufacturer Industry Group (SMIG) is a dedicated workstream supporting the innovation, policy priorities, and manufacturing needs of battery separator suppliers. These manufacturers produce a critical component of virtually every battery chemistry, including lead, flow, sodium, and lithium. They are essential to U.S. battery supply chains.
Separator design and material quality directly influence a battery’s energy density, cycle life, thermal stability, and safety performance. Through SMIG, BCI provides separator manufacturers with a forum to discuss technology development, engage on legislative and regulatory matters, and amplify the industry’s voice on issues affecting domestic manufacturing and market competitiveness across the full spectrum of battery chemistries.


The BCI Sodium Battery Industry Group (SBIG) is responsible for a broad scope of activities related to sodium-ion battery technology including, among others, testing, safety, statistics, and market development. It acts as a focal point for the application and commercialization of sodium batteries in North America. Chaired by Shawn Peng, CEO of QuantumShield Technologies, the SBIG was formed in 2026 to foster innovation, commercialization, and collaboration in this fast-growing chemistry.
As a primary driver for the industry, the SBIG monitors North American manufacturing trends to keep members informed of emerging demands and opportunities.
The group’s mandate includes executing strategic actions to accelerate commercialization and supply chain expansion while simultaneously educating stakeholders to stimulate market growth. Commitment to safety is a core pillar, with plans to develop protocols and best practices for sodium batteries and their related components. Additionally, SBIG aims to ensures technical consistency across the sector by establishing standardized test specifications, defining application parameters, and creating a unified operating terminology for sodium battery systems


The BCI Energy Storage Systems Initiative (ESSI) advocates for and supports the growing market for grid-connected energy storage systems by engaging federal and state regulators and utility companies to promote investment in battery research, development and deployment. The ESSI is chaired by BCI consultant John Howes, Principal at Redland Energy Group.
The ESSI operates from the perspective that when evaluating stationary energy storage options, federal and state policymakers should take a comprehensive approach that weighs cost, reliability, safety, performance, full life-cycle impacts, recycle rates, and scalability.
Federally funded research into stationary storage technologies should prioritize domestic battery industries, with particular emphasis on those that have an established and comprehensive circular infrastructure already in place. Utilities, meanwhile, should be encouraged to incorporate stationary battery storage system options into their integrated resource planning processes. Finally, BCI supports market-driven policies that create a framework for storage resources to participate in organized wholesale electricity markets, ensuring they are able to compete on a level playing field.


The BCI American Battery Research Group (ABRG) is a collaborative initiative dedicated to advancing battery performance, sustainability, and domestic manufacturing by bringing together industry leaders, researchers, and national laboratories to conduct scientific studies that enhance battery technology, improve recyclability, and strengthen the U.S. supply chain.
Led by Tim Ellis, BCI Technical Director, the ABRG pursues several key areas of focus. The group partners with institutions including Argonne National Laboratory and the University of Toledo to explore new materials, optimize battery lifecycles, and ensure energy storage solutions remain reliable, efficient, and environmentally responsible.
A core element of this work involves examining the molecular structure of lead battery expanders (lignosulfonates) in cooperation with the DOE’s Argonne National Laboratory and the University of Toledo, with financial support from U.S. lead battery manufacturers Clarios, Crown Battery, East Penn Manufacturing, EnerSys, and Stryten Energy.
To advance this research, the ABRG leverages sophisticated tools including high-throughput electrochemical test stations, DFT calculations, and machine learning to identify molecular parameters that enhance battery performance and inform predictive modeling. Collectively, this work supports the industry’s well-established circular economy by investing in research that extends battery lifespan, optimizes material recovery, and advances domestic battery manufacturing toward a more sustainable energy future.


The BCI Consortium for Lead Battery Leadership in Long Duration Energy Storage (LDES) brings together industry leaders and national laboratories to advance lead battery technology for a sustainable, resilient energy future. Supported by a $5 million Department of Energy grant, the Consortium focuses on achieving 10+ hours of storage capacity and reducing costs through research, techno-economic analysis, and material science. The Consortium pursues the following areas of focus:
Energy storage is going through a period of significant innovation and evolution. The team at BCI is helping the industry manage through those changes by providing industry forums and market data in a way that benefits all member companies.
